说明：  关于信号输入均匀量化器的信号幅度，用MATLAB实现量化过程(Uniform quantizer on the input signal amplitude, using MATLAB to quantify the process of achieving)

对于一个房间 用PID和DMC控制空调温度控制系统(For a room with air-conditioning temperature control PID and DMC control system)

The MATLAB code models a chain of transmission of an analog signal using FM modulation. 1-modulation signal_informatif ----> integrator ----> modulateurFM ---> modulated signal 2-demodulation modulated signal ---> differentiator -> rectifier -> fitrepasbas ---> DC component elimination the average DC component of the signal is removed in descriminant

three dimensional fin equation and area changing

频散方程的相速度和群速度曲线分析和绘制，带备注。(frequency dispersion)

m文件形式的无人机仿真模型，做到状态仿真阶段，后续可根据情况进行纵向和横向的设计(In the form of m file, an UAV simulation model,the state simulation stage have done, following it can be used to design the vertical and horizontal situation)

说明：  matlab图像退色处理源代码，imapprox函数方法(the matlab image fade processing source code, imapprox function method)

Gaussian processing regression

说明：  在matlab中，以simulink为主要工具介绍了系统仿真方法与技巧，包括连续系统、离散系统、随机输入系统和负数系统的仿真。(In matlab in order to simulink introduced as the main tool for system simulation methods and techniques, including continuous systems, discrete systems, stochastic systems and the negative input of the simulation system.)

当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)
